ltxfileinfo – Print version information for a LaTeX file

ltx­file­info dis­plays ver­sion in­for­ma­tion for LaTeX files.
If no path in­for­ma­tion is given, the file is searched
us­ing kpse­which.
As an ex­tra, for de­vel­op­ers, the script will
(use the --star or --color op­tions)
check the va­li­did­ity of the \Pro­vides...
state­ments in the files.
The script uses code from
Uwe Lück's read­prov.sty.
